How do i know if my erectile dysfunction is physical or psychological?

Ask yourself!: Are you anxious about your performance? I mean more so than average guy? Are you in a unhealthy relationship in which you're looking for a way out? Are you worried about work, money, family, friends, etc? Are you depressed? The above & more point towards a non-physical cause of ed. Smoking, drinking to excess, other illicit drugs, obesity, diabetes, high BP & cholesterol etc point to physical.
